Cyrus kicked off her weeklong residency on the Jimmy Fallon late-night program with a tribute to those affected by Sunday night's mass shooting.

Unity, peace and hopefulness. With that mantra in mind, Miley Cyrus kicked off her residency on The Tonight Show with a special tribute to the victims of the Las Vegas massacre.

Cyrus opened Monday night’s show on a somber note with a performance of Dido's "No Freedom,” calling on fellow guest Adam Sandler for support on guitar and backing vocals. “Peace everybody,” she shouted out as the song came to its close.

Cyrus dedicated the evening to those harmed by the shooting Sunday night at a country music festival which claimed at least 59 lives. “In honor of the lives lost, injured and affected by the tragic shooting in Vegas, [The Tonight Show Starring Jimmy Fallon] & I dedicated this show to not only mourning this horrific event but using this platform to encourage unity, peace & hopefulness!,” she tweeted ahead of the show.

And after the program went to air: "No Love without Freedom...No Freedom without LOVE. Thank you so much to Adam Sandler for joining me tonight in remembering all those lost," she wrote.

The "No Freedom" performance was the first in a weeklong guest stint on the Tonight Show for Cyrus which will involve appearances in sketches, interviews and, of course, more musical performances, including a rendition of "The Climb," the hit country-pop power ballad that dates back to her Hannah Montana days.
